MEASURING-PUMP.

Specification of- Letters Patent.

Patented June 15, 1915.

To all whom it may concern Be it known that I, FLAVIUS J. YOUNG, a citizen of the United States of America, and resident of Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Measuring-Pumps, is a specification.

This invention relates to improvements in measuring pumps, and the objects thereof are: First, to provide a pump for dispensing liquid and so constructed as to discharge a definite quantity of liquid upon each complete operation of the pump, and also disin such fractional units of measurement asmay be desired upon corresponding operations of the pump; second, to provide devices in connection with the pump for regulating its operations and indicating the quantity of liquid discharged therefrom; and third, to afl'ord a lock to prevent unauthorized operation of the pump. These objects are accomplished by the construction illustrated in the accompanying drawings in which Figure 1 is a front elevation of the pump; of the same; Fig. 3 is a detail view showingthe locking device partly in section; Fig. 1 is adetail' view of the lock; Fig. 5 is a detail View showing a plan of one of the stops partly in section; Fig. 6 is a detail view showing a side elevation of the register partly in section ;v and Fig. 7 is.a detail view showing a front elevation of the same, partly cut away.

- Similar numerals of reference indicate corresponding partsthroughout the several views, and referring now to the same: 1 is a pump cylinder having therein a plunger 2 connected with and drivenby a pump rod Thepump proper may be of any suitable construction" adapted to effect the discharge of liquid out through the discharge spout 4 that leads from the cylinder. Such pumps being in common use, and well understood, the illustrations here represented of the pump proper have not been made complete, especially with respect to the customary valves.

The invention relates more particularly to the mechanism for operating, controlling, and regulating the pump proper, and comprises a standard 5 erected above the cylinder with a crank 6 mounted at its upper part. A rack 7 is secured to the pump-rod of which the following 3 and has connection in the housing 8, by means of gears 9, with the crank,so as to be driven up or down accordingly as the crank is turned.

A scale 10 is secured to the rack 7 in parallel relation therewith, and moves with the rack, and an indicating finger 11 is fixed on the housing in proximity to the scale to designate Where the scale is to be read. By this arrangement the operator is not obliged to shift the direction of his vision in making successive readings, and can readily locate the proper place on the scale for reading as the finger is always in the same location.

At the lower end of the rack 7 is a pro- "jecting lug 12, and upon the standard 5 is pivoted one or more adjustable stops 13-14 adapted to be turned so as to engage the lug 12 as the rack rises and arrest its upward movement. The stops are bolted sufficiently tight as to be frictionally held in their adjusted positions. Each stop has an arm 16 provided with an adjusting screw 17 which is adapted to engage the lug 12 directly when the stop is in engaging position. Projecting shoulders 1819 on the standard serve respectively to block the turning movement of the corresponding stops 1314, when the latter reach their proper active position. The locations of the several stops upon the standard are such as to afford means to limit the upward or discharging movement of the pump rod to a fractional portion of its full stroke as desired. For example: The stop 13 may be located so as to engage the lug 12 and thus arrest the upward movement of the rod at one-fourth of its stroke; and the stop 14 likewise arranged to act at one-half the stroke.

Upon the housing 8 is mounted a register 19 having an operating lever 20, and upon the top of the rack 7 is a lug 21 adapted to come into contact with the lever 20 at the completion of the downward movement of the pump rod, and actuate the lever. The register 19 consists of a base 22 having a dial 23 upon which is arranged a concentric series of indicating numerals 7, 8, 9, 0, 1, etc. A revolulole disk 2-1- is mounted upon a screw 25 that extends centrally from the dial, and has a sight opening 26 through which may be observed singly in succession the indicating numerals as the disk 15 revolved. A handle 27 fixed on the disk serves 50 discharged. Should both stops be set as the to adjust the same manually. Upon the rear side of the disk is a series of teeth 28 adapted to be engaged by a ratchet 29 that is carried by the lever and held in contact with the teeth by a tension spring 30. The active end of the ratchet extends through an opening 31 in the dial, which is so proportioned as to allow the ratchet to shift the disk upon movement of the lever 20. A pair of dished washers 32, placed with their convex sides together are interposed between the dial and disk to frictionally detain the disk from unintended movements. A screw 34 in the lever 20 affords means for precise adjustment between the lever 20 and the lug 21 on the rack.

Another feature of the invention is in-the locking device for securing the crank, and it consists of a lock 35, which is of the snap type, fixed on the standard, and a sliding.

bolt 36, arranged in the handle 37 of the crank 6. Over the lock is a shield 38 adapted to receive the bolt 36 and hold it 'in engagement with the latch 39. The bolt has a tapered end 40 and a notch 41, and the former acts to depress the latch as the bolt is shifted into the shield, while the latter receives the latch as it springs into locking position. The handle 37 has a chamber 42 containing a spring43 that acts against a collar 44 on the bolt to hold the latter from engagement with the lock, and a sleeve-nut 45 in the end of the handle acts as a backstop for the bolt; by engaging the collar oppositely to the spring.

In the operation of the invention, the latch is withdrawn from engagement with the bolt by inserting a key into the lock in the usual manner, whereupon the spring43 will withdraw the bolt 36 from the shield 38 of'the lock, and the crank may then be operated. If the stop 13 be set as in Fig. 2, the lift of the pump rod will be restricted by contact of the lug 12 and the stop so that only a fractional part of the contents of the pump cylinder Wlll be dischar ed upon the operation of the crank; and 1f the stop 14 be likewise set instead of the former stop, the movement of the pump rod willi be greater and a correspondingly larger fractional part of the contents of the pump cylinder will be stroke,

stop 14 is shown in Fig. 2, the pump-rod would make its full stroke upon operation of the crank and a complete discharge-from the pump would be obtained. In filling a vessel of unknown capacity, where the amount I of liquid required is less than one complete discharge of the pump, the crank is turned until the vessel is filled and the amount discharged is then ascertained by reading the scale at the instance of the finger 11; and

in filling a vessel having a capacity of many times one complete discharge of the pump, the pump is operated repeatedly at full and as the disk is actuated at the completion of each downward stroke of the engaging said lug; and means for actuating the pump.

2. In apparatus of the class described, a pump having a reciprocating pump-rod; a lug in fixed relation with the pump-rod; a mechanism for "actuating the pump-rod; a standard for supporting the mechanism and having thereon one or more pro ecting shoulders; and one or more stops adjustably mounted on the' standard, said stops being adapted to be blocked by the corresponding shoulders, said .lu'g being adapted to engage any of the stops when blocked to arrest the movement of'the' pump-rod in itsupward stroke.
